In order to write sentences in the Future Perfect Simple, we write the subject followed by the modal verb Will ('ll) and the auxiliary "Have". Then we write the main verb of the sentence in Participle.

If the verb is regular, the participle goes with -Ed at the end of it.

Play > Played

Work > Worked

Live > Lived

If the verb is irregular, the participle form appears in the 3° column of the irregular verb list.
